Having more than one is good, having more than required just adds to the trouble they cause every so often.

[ADDED] well done; being able to easily move and add a disk from one machine to another is one of the big advantages of a desktop machine over a laptop... [/ADDED]

You're making the assumption that he can even get to the prompt to start in safe mode. Usually, with a problem like this, you don't get that far.

Why would you want to do that?
If you want to experiment with some assembly, the easier way is to create an application using a high-level language (say C) and implement one function (or part of a function) with assembly,
e.g. using the asm keyword you can embed assembly code right in C code.

One potentially useful exercise would be to get the CPU capabilities exposed by the CPUID instruction.

Tricky, you could try this:

Your will have to load a filter driver on your device and at one of the start IRPs such as IRP_MJ_STARTDEVICE block the IRP and wait for the app to supply the uname pwd. The app would do this via a dedicated device object created by the filter driver.

On a sucessfull entry the filter completes the IPR as success. On fail it completes it as failure and the system will unload the device stack.

It is possible that the OS wil timeout the IRP though, inwhich case you could try another, or wait for the device to start and then block all read/write/URB/IOCTL IRPs untill you get a valid uname-pwd. If you dont you could call an invalidate bus relations and fail the start device thereafter.

If there was no reason to hang, then it wouldn't.

XP has an aversion to VB "development. That's why Microsoft released Vista - it's much more tolerant of VB.

I think you need to take backup of all files and reinstall your OS.
Or clean your system. Remove unwanted application etc
